An object of the present invention is to provide an EL display device having high operation performance and reliability.
A third passivation film
45
is disposed under the EL element
203
comprising a pixel electrode (anode)
46,
an EL layer
47
and a cathode
48,
and diffusion of alkali metals from the EL element
203
formed by ink jet method into TFTs is prevented. Further, the third passivation film
45
prevents penetration of moisture and oxygen from the TFTs, and suppress degradation of the EL element
203
by dispersing the heat generated by the EL element
203.
